Research dispels myth that COVID-19 vaccines cause infertility, but misinformation persists

Some sources of misinformation claim that the COVID-19 vaccines cause male sterility. For this to be true, the vaccines would have to damage sperm quality, drastically reduce sperm count or interfere with the mechanisms inherent in male ejaculation. Quality clinical evidence has demonstrated that none of these parameters are affected by the vaccine, so men are not being made sterile. A study in Florida recruited around 45 men and compared their sperm measures before and after receiving a COVID-19 vaccine. Interestingly, the study found that men who received the vaccine had more sperm, greater semen volume, and sperm more able to move around and fertilize an egg. Pregnancy can be an exciting time but can also provoke worry about the the safety of anything that enters the body, including vaccines. Fortunately, the COVID-19 vaccines are safe during pregnancy.
